Exchange based tokens don't fluctuate as much as other tokens do. I have been following the Ku coin exchange token for a long time and what I see is that when the market is bullish or when BTC goes up, the price of those coins goes up and when BTC goes down it goes down. In 2021 the token price of Ku Coin exchange platform was $17 per coin currently trading between $6. So these coins seem to depend a lot on the price of Bitcoin. If one wants to hold the coins of this exchange platform then one must hold for long term otherwise the chances of loss will be high.
Do you refer to KCS (token of Kucoin exchange)?
I think KCS fluctuates the same as other tokens. Its ATH is around $28 and the current price is $7,8. The difference between its ATH and current price is quite a lot, also the price never stable in a certain rate everyday. It means the token fluctuating normally as other tokens. If it doesn't increase significantly, it is because the current trend of Bitcoin. We must know that Bitcoin still increases gradually, it may increase significantly after the halving. If you expected the price will be above $17 again, just wait until the halving is over.
Anyway, people usually wait for the altcoin season to trade their altcoins. If you want to sell your KCS, just wait the altcoin season that probably happens in 2024-2025.
